Notice to user
IMPORTANT!
Please read the following section before installing your product:
Octagon’s products are designed to be high in performance while consuming
very little power. In order to maintain this advantage, CMOS circuitry is
used.
CMOS chips have specific needs and some special requirements that the user
must be aware of. Read the following to help avoid damage to your card from
the use of CMOS chips.
≡ Using CMOS circuitry in industrial control
Industrial computers originally used LSTTL circuits. Because many PC
components are used in laptop computers, IC manufacturers are exclusively using CMOS technology. Both TTL and CMOS have failure
mechanisms, but they are different. Described below are some of the
failures which are common to all manufacturers of CMOS equipment.
However, much of the information has been put in the context of the
Micro PC.
Octagon has developed a reliable database of customer-induced, field
failures. The average MTBF of Micro PC cards exceeds 11 years, yet
there are failures. Most failures have been identified as customerinduced, but there is a small percentage that cannot be identified. As
expected, virtually all the failures occur when bringing up the first
system. On subsequent systems, the failure rate drops dramatically.
n Approximately 20% of the returned cards are problem-free. These
cards, typically, have the wrong jumper settings or the customer has
problems with the software. This causes frustration for the customer and incurs a testing charge from Octagon.
n Of the remaining 80% of the cards, 90% of these cards fail due to
customer misuse and accident. Customers often cannot pinpoint the
cause of the misuse.
n Therefore, 72% of the returned cards are damaged through some
type of misuse. Of the remaining 8%, Octagon is unable to determine the cause of the failure and repairs these cards at no charge if
they are under warranty.
Notice to user
PC-500 user’s manual
The most common failures on CPU cards are over voltage of the power
supply, static discharge, and damage to the serial and parallel ports.
On expansion cards, the most common failures are static discharge, over
voltage of inputs, over current of outputs, and misuse of the CMOS
circuitry with regards to power supply sequencing. In the case of the
video cards, the most common failure is to miswire the card to the flat
panel display. Miswiring can damage both the card and an expensive
display.
n Multiple component failures - The chance of a random component failure is very rare since the average MTBF of an Octagon card
is greater than 11 years. In a 7 year study, Octagon has never
found a single case where multiple IC failures were not caused by
misuse or accident. It is very probable that multiple component
failures indicate that they were user-induced.
n Testing “dead” cards - For a card that is “completely nonfunctional”, there is a simple test to determine accidental over voltage,
reverse voltage or other “forced” current situations. Unplug the card
from the bus and remove all cables. Using an ordinary digital
ohmmeter on the 2,000 ohm scale, measure the resistance between
power and ground. Record this number. Reverse the ohmmeter
leads and measure the resistance again. If the ratio of the resistances is 2:1 or greater, fault conditions most likely have occurred.
A common cause is miswiring the power supply.
n Improper power causes catastrophic failure - If a card has had
reverse polarity or high voltage applied, replacing a failed component is not an adequate fix. Other components probably have been
partially damaged or a failure mechanism has been induced. Therefore, a failure will probably occur in the future. For such cards,
Octagon highly recommends that these cards be replaced.
n Other over-voltage symptoms - In over-voltage situations, the
programmable logic devices, EPROMs and CPU chips, usually fail in
this order. The failed device may be hot to the touch. It is usually
the case that only one IC will be overheated at a time.
n Power sequencing - The major failure of I/O chips is caused by the
external application of input voltage while the Micro PC power is off.
If you apply 5V to the input of a TTL chip with the power off, nothing will happen. Applying a 5V input to a CMOS card will cause the
current to flow through the input and out the 5V power pin. This
current attempts to power up the card. Most inputs are rated at
25 mA maximum. When this is exceeded, the chip may be damaged.
n Failure on powerup - Even when there is not enough current to
destroy an input described above, the chip may be destroyed when
the power to the card is applied. This is due to the fact that the
input current biases the IC so that it acts as a forward biased diode
on powerup. This type of failure is typical on serial interface chips.
PC-500 user’s manual
Notice to user
n Hot insertion - Plugging cards into the card cage with the power on
will usually not cause a problem. (Octagon urges that you do not
do this!) However, the card may be damaged if the right sequence
of pins contacts as the card is pushed into the socket. This usually
damages bus driver chips and they may become hot when the power
is applied. This is one of the most common failures of expansion
cards.
n Terminated backplanes - Some customers try to use Micro PC
cards in backplanes that have resistor/capacitor termination networks. CMOS cards cannot be used with termination networks.
Generally, the cards will function erratically or the bus drivers may
fail due to excessive output currents.
n Excessive signal lead lengths - Another source of failure that was
identified years ago at Octagon was excessive lead lengths on digital
inputs. Long leads act as an antenna to pick up noise. They can
also act as unterminated transmission lines. When 5V is switch
onto a line, it creates a transient waveform. Octagon has seen
submicrosecond pulses of 8V or more. The solution is to place a
capacitor, for example 0.1 µF, across the switch contact. This will
also eliminate radio frequency and other high frequency pickup.
≡ Avoiding damage to the heatsink/CPU
WARNING!
When handling any Octagon CPU card, extreme care must be
taken not to strike the heatsink against another object, such
as a table edge. Also, be careful not to drop the CPU card,
since this may cause damage to the heatsink/CPU as well.
Epoxy adhesive bonds the heatsink to the CPU chip. When
the heatsink is struck, the epoxy adhesive does not allow the
heatsink to separate from the chip. The force of the blow to
the heatsink then causes the legs of the CPU chip to separate
from the PCB. This force damages both the CPU chip and
the PCB.
Note
Any physical damage to the CPU control card is not covered under
warranty.

≡ Description
The PC-500 Mobile Industrial Computer™ (MIC) is a high performance,
single board PC in Octagon’s semi-custom product line. The PC-500
integrates serial communication, industrial digital I/O, a floppy and
local bus hard disk port, a multifunctional parallel port, and a local bus
video which supports monitors and flat panels. This single board computer has an interrupt routing matrix, two solid-state disks, a PC/104
interface, a SCSI-2 interface host port, and a 10Base-T Ethernet port.
The PC-500 also supports various CPU types including 586/133 MHz
and can have up to 16 MB of on-board DRAM with an expansion of
48 MB by adding a 32 MB DIMM module. This board is supplied with
DOS 6.22 in ROM but will also execute other operating systems such as
Windows™, Windows NT™, and QNX®. Since the PC-500 uses the
same functional blocks as the Micro PC™, the circuitry has been fully
proven as reliable and the software is compatible with the software in
the Micro PC series.
Specified to your engineering needs, the PC-500 can be ordered as a
semi-custom board in OEM quantities. The stocked version of the
PC-500 is listed below with the standard and optional features. The
standard version can be used for system development and an optional
version of the PC-500 is usually application specific.
≡ PC-500 major hardware features
CPU
The high performance 586 CPU comes in two versions. One version is a
120MHz586 and the other is a 133MHz586. Both versions operate at
3.3V for low power consumption. The PC-500 has a local bus speed of
33 MHz and an ISA bus speed of 8.33 MHz.
Up to 48 MB DRAM
The standard unit is supplied with 1 MB of fast, EDO surface mount
DRAM. The use of EDO DRAM increases performance by 20% which, in
most cases, eliminates the need for an expensive L2 cache. The PC-500
can contain up to 16 MB of on-board DRAM. Up to 32 MB of additional
DRAM can be added through an optional DIMM module, which makes a
total of 48 MB DRAM. Two holes are on-board the PC-500 to secure the
DIMM module in high vibration environments. All surface mount

Solid-state disks
SSD0
A 32-pin DIP socket accepts either a 5V flash, SRAM, or 512 KB/1 MB
EPROM. The socket exhibits high retention force and affords a gas
tight contact. SSD0 optionally contains the BIOS drive and ROM-DOS
6.22 in ROM. By default, the optional SSD0 contains a 192 KB backup
BIOS with a 320 KB or a 512 KB drive area. Flash file system software
is included which allows the SSDs to emulate hard disk operation.
SSD0 options include:
n SSD0 socket installed
standard
n SSD0 socket not installed
optional
n SSD0 socket/EPROM installed
optional
For information on changing the device type, refer to the W5 SSD0
table in the Quick start chapter. You can also install compatible
PROMs into SSD0 through the supplied utility programs found on the
PC-500 utility disk. You can format the flash while in the socket.
EPROM usage, however, requires off-card programming from either a
master flash or a master EPROM.
SSD0 also supports a battery back up voltage. The PC-500 is capable of
supplying a battery voltage to SSD0 with SRAM installed.
SSD1
SSD1 is used for storage of the applications program. A standard 2 MB
5V flash is soldered on-card. The flash programmer is built-in which
allows on-card programming of the device. The PC-500 includes flash
file system software, which permits the SSDs to emulate hard disk
operation. Automatic “wear leveling” ensures that no single section of a
chip will reach its life span (100,000 times), while other sections will
scarcely be used. A 1 MB device reserves 192 KB for BIOS and 832 KB
for a drive area, a 2 MB device reserves 192 KB for BIOS and 1856 KB
for a drive area.

n Mouse port included
n Mouse port not included
standard
optional
PC/104 16-bit interface
This interface is a standard feature on the PC-500 and accepts an 8- or
a 16-bit PC/104 expansion board. PC/104 expansion boards are available from several manufacturers. As many as three PC/104 expansion
boards may be stacked on the PC-500.
Ethernet
The PC-500 provides a 10Base-T Ethernet port, located at J9. This
interface is a standard feature on the PC-500 and supports the IEEE
802.3 Ethernet standard. The Ethernet controller IC chip provides the
following:
n 16-bit ISA interface
n 4 KB on chip buffer
n Integrated 10 Base-T transceiver interface
n Four LEDs for status and diagnostic purposes
The PC-500 Ethernet interface supports the 10Base-T physical interface. This port operates at 10 MHz and uses twisted-pair wiring cable,
which is built in a star configuration. The 10Base-T physical interface
terminates at the standard, 8-position RJ-45, latching phone jack and is
vertically accessed.
SCSI
The PC-500 has a SCSI-2 host interface, located at J12. This device is a
16-bit ISA bus compatible part and has a sustained data rate of 10 MB

≡ PC-500 major software features
Advanced power management and system management
input
Power management can be used to reduce power consumption or to
freeze the state of the program on the occurrence of a power management interrupt. Power consumption can be reduced by more than 60%.
This reduces the heat load and extends the battery life in mobile applications. There are opto-isolated system management and suspend/
resume inputs with 4-6V ranges. A system management input (SMI)
will cause the PC-500 to save its current status. When the system is
signaled to restart, execution resumes at the point the system last
stopped. The following are functions in the advanced power management and SMI:
n Suspend/resume by SMI input and software — halts CPU
n Wake up through various interrupts including keyboard, SMI
and serial port
n Slow CPU by dividing clock
n Contextual save to disk.
Diagnostic software verifies system integrity automatically
The PC-500 has built-in diagnostic software that can be used to verify
on-card I/O and memory functions. On powerup, a series of tests is
performed. If a problem occurs, the failed test can be identified by the
color sequence on an on-board, bicolored LED. The test is performed
automatically every time the system is reset or powered up. Software,
test equipment, monitor, keyboard, disks, or test fixtures are not required for memory verification. See the LED signaling “beep” codes
chapter for a complete listing of tests and failures and their descriptions.
SETUP information stored in EEPROM for high reliability
Loss of SETUP data is serious in industrial applications. Most PCs
store SETUP information in battery-backed CMOS RAM. If the battery
fails or is replaced during routine maintenance, this information is lost.
Without a keyboard and monitor in embedded applications, time consuming re-initialization is required. The PC-500 stores the SETUP
information in EEPROM with 1,536 bytes available to the user. Software routines to use this available memory come with the PC-500.
1-5
Overview
PC-500 user’s manual
Phoenix BIOS
The PC-500 has a Phoenix AT BIOS with power management and
Octagon BIOS extensions. The AT BIOS supports up to four EIDE
drives.
“Instant DOS” operating system
Datalight ROM-DOS v6.22 operating system is in flash. This means
that this version is always present on powerup. The system boots and
operates the same way as a desktop PC. Since all software and hardware are included, the system is fully operational “out of the box.”
Programmable video BIOS
The flash contains a video BIOS, which controls the on-board SVGA
controller. To support other flat panels, you can reprogram a new video
BIOS. By default, the video BIOS supports a CRT and Sharp monochrome dual drive flat panel in simultaneous mode.
On-board flash file system
The Phoenix PICO FA flash file system controls the on-board SSDs,
which allows read/write DOS access to the flash/SRAM. SSD0 can also
use EPROM. For certain types of flash, the flash file system uses “wear
leveling” to spread the usage and maximize the lifetime of these devices.
Octagon BIOS extensions
On-board BIOS extensions allow easy access to digital I/O, serial
EEPROM, LCD bias control, watchdog timer functions, etc.
Interrupt routing: In system and programmable
Software is on-board the PC-500 to change the interrupt routing and
some other features. The software allows more flexible use of interrupts on the PC-500 and outboard systems such as PC/104 expansion
boards.
Floppy and hard disk ports
The floppy disk port supports two drives with either 720 KB or 1.44 MB
capacities. The floppy port is terminated with a 34-pin IDC connector.
The EIDE hard drive port is terminated with a 44-pin, 2 mm connector.
+5V is supplied to the hard drive through the EIDE connector and is
optionally supplied to the floppy drive through the IDC connector.

Watchdog timer added for safety
The watchdog timer resets the system if the program stops unexpectedly. The watchdog is enabled, disabled and strobed under software
control. The time-out is 1.6 seconds (typical).
Real time calendar/clock with battery-backup
The real time clock is fully AT compatible and uses the standard DOS
calls. An optional off-card battery powers the real time clock when the
5 volt supply is removed. A connector is provided for the external battery. The real time clock also provides the user with 128 bytes of userdefined CMOS-RAM.
I/O connectors
With the exception of the mouse, keyboard, and IDE, all I/O connectors
can be latched to prevent connector movement during shock or high
vibration.
Keypad and LCD display support for low cost operator
interface
For embedded applications, the parallel printer port or the EZ I/O port
can interface with a 16-key matrix keypad and a 2- or 4-line LCD display. The PC-500 is supplied with software that provides keypad scanning and display operation. Supplied display and keypad drivers in C

5 Volt operation lowers system cost
The PC-500 operates from a single 5V ±5% supply. Located across the
power supply, the 6.2V, 5W zener diode protects against reverse voltage
and limits over voltage. The power supply generates the RS-232 voltages
on-board. The locking power connector is a standard PC power header
connector.

≡ PC-500 power supply requirements
The PC-500 is designed to operate from a single +5 VDC supply. An AT
compatible power supply connector header (P8, P9) is on board and
ensures the required number of power and ground paths from the power
supply. Make sure that you utilize all three +5 VDC conductors and all
four ground conductors.
The power connector at P8, P9 also provides +/-12 VDC and -5 VDC
required for any PC/104 expansion board. P8, P9 also supplies the
correct voltage, +12 VDC, for flat panels that require back light operation. Refer to the P8, P9 power connector Table 2-1 for a complete
listing of pinouts and their description.
The maximum current requirements for the PC-500 is 2.0 A provided
through P8, P9. It is important that a quality power supply be used
with the PC-500. For example, when a particular application calls for a
custom power supply, there are several internal issues to consider such
as current capacity, line and load regulation, maximum ripple, hold up
time, efficiency, and current limiting. The user should also consider the
power devices and equipment such as the power cable conductor gauge,
number and length of conductors, mating connectors, and the power
supply to external devices such as hard drives, floppy drives, displays,
mouse, and keyboard.
The proper selection of a quality power supply ensures reliability and
proper functioning of the PC-500.
WARNING!
Make sure the power supply is OFF when connecting the
power cable to the PC-500 board. Damage to the PC-500 may
occur if the power is ON when connecting the power cable.

SETUP programs
SETUP programs
≡ Introduction
Three system configuration programs exist for the PC-500. They are:
n SETUP – Configures devices set up by the BIOS such as serial ports
and floppy drives
n SETSSD – Configures PICO FA SSD device order
n PMISETUP – Configures power management options at a more
detailed level than SETUP
n SETIRQ – Configures the interrupt routing matrix.
≡ SETUP
SETUP can be entered in one of two ways:
n Run SETUP.COM
n Press the “backspace” key followed by the “S” key during BIOS
POST sequence (this occurs between the memory test and boot).
Also, by removing the USESETUP jumper from W2[9-10], you may
force the setup to temporarily revert to the BIOS defaults (Table 3-1)
and also allow the user to reconfigure the setup options.
The SETUP program defines the PC-500 system parameters. This
program is shipped with default configuration parameters stored in
the serial EEPROM. Changes are made by running the SETUP
program. The SETUP program is stored on the SSD1 drive and on
the PC-500 utility disk.

you reboot the PC-500, your program can automatically load into DOS
memory and execute. As shipped from the factory, SSD1 already contains a bootable ROM-DOS.
This chapter describes the following:
n Saving an application program to SSD1
n Autoexecuting the program from the PC-500
n Overriding autoexecution of your program.
The information in this chapter assumes you are using ROM-DOS in
your application. Some Microsoft programs make undocumented DOS
calls. With ROM-DOS, an error returns when an undocumented DOS
call is made, causing your program to operate erratically. We recommend booting from SSD1, using your own DOS, when using programs
with undocumented DOS calls. Refer to the section Adding operating
system startup files in the Managing SSDs chapter for more information
on saving and autoexecuting programs.
≡ Saving programs and support files
By default, the drive in SSD1 comes preformatted from the factory,
loaded with ROM-DOS startup files and an example demo program. To
replace the demo program on SSD1 with your own, see the section
Adding your application, in this chapter. To reformat an SSD or to add
your own operating system, please refer to the Managing SSDs chapter.
WARNING!
Reformatting SSD1 requires the use of a floppy or a hard
disk to restore system files.

Adding your application
To add your application to your SSD, do the following:
1. Three methods of copying your application to the SSD are available. Do
one of the following:
n From a local drive to the PC-500, issue the COPY command.
n From a host drive, download your application by issuing the
TRANSFER command when using PC SmartLINK. Refer to the
section, Transferring files between the PC-500 and your PC in the
Transferring files/remote disks chapter.
n To establish a remote drive and copy from it, issue the REMDISK
and REMSERV commands. Refer to the section, Transferring files
between the PC-500 and your PC in the Transferring files/remote
disks chapter.
2. Add or remove any device drivers for your application. You may want to
do the same for the CONFIG.SYS file on SSD1. Remember to add these
drivers to your drive as well.
3. To autoexecute your application, add your application name to the
AUTOEXEC.BAT file. To replace our example program (DEMO.EXE)
with your application, substitute DEMO in the AUTOEXEC.BAT file
with your applications’ filename.
Autoexecuting your application
This section describes how to autoexecute your application.
1. To autoexecute your application in SSD1, use the SETSSD command to
define your SSD as the boot device. Since you need to define the order
of SSD1 as the first of the SSDs (and before any IDE drives), enter the
following command:
PC500 C:\> SETSSD SSD1 SSD0 /before
2. Reset the system. SSD1 is now drive C: and your application should
begin execution.
Note
If the SETUP option “Boot Sequence” is set to “A: THEN C:”, remove
any floppy in drive A: before resetting the system.
Note
We recommend that you leave SSD0 in the SETSSD options or that you
have a copy of SETSSD.EXE on SSD1. This allows you to change your
boot device back to SSD0 when needed.
Note
The SETSSD options are not used when W2[9-10] is not jumpered.
Overriding the autoexecution of your application
You may stop the autoexecution of your application by doing one of the
following options:

COM3 through COM5 interrupt/status port
COM3 through COM5 share the same interrupt—they default to IRQ15.
To determine which serial port caused the interrupt, you must first read
the interrupt status port. Follow these steps to read the interrupt
status port:
1. Read register 0A9h to read the I/O range select A (bit 5) and I/O range
select B (bit 4) information. See Table 5-5.

For example, if bits 5 and 4 are both 0, the interrupt status port addresses are 158-15Fh. If bit 5 is 0 and bit 4 is 1, the interrupt status
port addresses are 138-13Fh; if bit 5 is 1 and bit 4 is 0, the interrupt
status port addresses are 358-35Fh; and if bits 4 and 5 are both 1, the
interrupt status port addresses are 338-33Fh.
3. Inside your interrupt handler, read the interrupt status port. Bit 3
through bit 6 show which serial port caused the interrupt.
For example, when there is a 1 in bit 3, this means COM3 caused the
interrupt; a 1 in bit 2 shows that the interrupt came from COM4; a 1 in
bit 1 means that COM5 caused the interrupt; and by default, when a 1
is in bit 0, then COM5 caused the interrupt. See Table 5-6.
Note

COM5
COM can be configured either as an industrial 2-wire RS-485 port or a
2-wire TTL serial port. COM5 uses the RTS pin to enable or disable the
RS-485 transmit/receive function. That is, a logic ‘1’ in bit position 1,
register offset 4, will enable the transmitter function and disable the
receiver function. A logic ‘0’ in bit position 1, register offset 4, will
disable the transmitter function and enable the receiver function.
The interrupt, IRQ15, for COM5 is logically OR’d with COM3 and
COM4. Interrupt routing for COM5 is configured through the interrupt
routing matrix. COM5 is located at J17. For more information, see the

≡ Function and use of serial ports
COM1 as serial console device
Instead of the on-board local bus SVGA, you can use COM1 as the
console device. See the Console devices chapter for more information.
When COM1 is not used as a console device, then it is available to your
program as a standard RS-232 port. Octagon Systems strongly urges
that you leave COM1 at the 3F8h default address.
COM1 through COM4 as RS-232 I/O
COM1 through COM4 can also be used as RS-232 serial ports. Depending upon the design of each port, COM1 through COM4 can support
4- or 8-wire configurations. Use a VTC-20F cable to interface from the
PC-500 to the serial device.

COM5 as RS-485 transmitter control
COM5 can either have a 2-wire RS-485 or a 2-wire TTL interface. The
default configuration is for an RS-485 port. To change the default
configuration from RS-485 to TTL, refer to Table 5-19.
COM5 defaults to base address 320h. The RS-485 transmitter is controlled by the COM5 RTS signal. To turn the transmitter ON and OFF
through software control, toggle bit 1 of base address + 4 (323h). Refer
to the following table on RS-485 terminations.

The RS-485 port is configured for termination for either marking or
spacing idle condition, or not terminated. Any node located between the
end points should not be terminated. Use W1[1-2][3-4] to disable termination. Jumper W1[7-9][8-10] to provide for marking condition and
make sure that both ends of the network are terminated.

≡ RS-485 network
An application may implement a node as either the “host” node or as a
“remote” node in an RS-485 network. There can be as many as 32 nodes
without any bus repeaters in the network. A “host” is referred to as the
node that initiates communication; while a “remote” is referred to as a
node that is addressed by the host.
In any given communication sequence in an RS-485 network, there can
only be one host. The host is responsible for initiating communication,
maintaining network registration, and providing housekeeping tasks
with other nodes. Remotes, however, cannot initiate a communication.

They can only respond to messages that are addressed to them from the
host.

Console devices
≡ Description
The PC-500 has three options for console devices. You can use the onboard video with a monitor and a keyboard as your console. You can also
use COM1 as the console or you can run the system without a console
device.
≡ Selecting console devices
The following represent the PC-500’s three options for console devices:
n Local bus SVGA and a local keyboard. The local bus SVGA can also
drive flat panel displays.
n Serial console from COM1. A serial cable/null modem adapter plugged
into a host PC running SmartLINK provides both input and output.
The local keyboard also allows input.
n No console device means no video output, either from the SVGA monitor or the serial console. The local keyboard allows input.
Local bus SVGA
For correct usage of the CRT and flat panel, see the CRTs and flat panels
chapter.
Serial console
If the serial console is enabled and the video BIOSes are disabled, then
COM1 is used as the console device.
Follow these steps to use the serial console:
1. Power off the PC-500.
2. Connect a VTC-20F to J7 of the PC-500. Refer to Figure 7-1.
3. Connect P2 (COM1 side of the VTC-20F cable) to the 9-pin null modem
adapter. Refer to Figure 7-2.

Console devices
Keyboard
You can use any of the console options mentioned in the Selecting console
devices section with a local keyboard.
Speaker
You can also use a local speaker with any of the console options listed
above in the Selecting console devices section. Interface the speaker via a
4-pin connector at J4. You may use any external speaker from 8-50 ohms.
Mouse
You can also add the use of a mouse to the list of serial console devices
mentioned in the Selecting console devices section in this chapter. The
mouse connects to J3 on the PC-500.
Note
See the Accessories appendix for mating information on the keyboard,
speaker, and mouse connectors.
≡ Enabling/disabling the video BIOS
The BIOS checks for a video BIOS to determine which console device to
use. If a console device exists, the BIOS will use the console device, the
CRT, or the flat panel. When the console device does not exist, the BIOS
will otherwise use a serial console, if it has not been disabled in SETUP.
To enable/disable the video BIOS area, either change W2[1-2]/W4[1-2] or
run SETUP and change C0000h-C7FFFh or C8000h-CFFFFh ROM
enable options. The jumpers work as a toggle for the SETUP options.
That is, if the SETUP previously shows the BIOS regions as “enabled,”
then changing the state of W2[1-2]/W4[1-2] will disable the regions.
To verify the SETUP program’s state for the C0000h-CFFFFH regions,
remove the USESETUP W2[9-10] and install W2[1-2] and W4[1-2]. This
jumper installation enables the video BIOS areas. To allow for serial
console use, disable the video BIOS areas by removing W2[9-10] and
W2[1-2]/W4[1-2]. See Table 7-1 and Figure 7-3 as reference guides for
disabling and enabling the video BIOS and changing ROM enable.

SSDs, DRAM, and battery backup
≡ Description
Before you can save and boot your application from the PC-500, you must
first configure the system for your particular application requirements.
≡ SSD0 (optional)
SSD0 is an optional feature and is not installed on the standard version of
the PC-500.
WARNING!
Incorrect installation of SSD0 will destroy the chip. To install
SSD0, be sure to match the notch in the SSD0 chip with the
notch in the SSD0 marked silkscreen on the PC-500.
A flash, SRAM, or EPROM device may be installed on the PC-500.
Jumper blocks W2[7,8] and W5 must be set appropriately. See Table 8-1
for settings.

≡ SSD0 replaced with an SRAM device
Before replacing SSD0 with an SRAM device, do the following steps:
1. Power off the PC-500 and then make sure to jumper W2[5-6] is jumpered
in order to boot from the BIOS on SSD1.
2. Since SSD0 is to be replaced with an unprogrammed device, the PC-500
must be configured to boot from SSD1. Run SETSSD.EXE to change the
boot device:
PC500 C:\> SETSSD SSD1 SSD0
8-1
SSDs, DRAM, and battery backup
PC-500 user’s manual
3. Power off the PC-500 and install a 512K SRAM into SSD0 at socket
U21. Both W5[1-3, 2-4, 5-7, 8-10] and W2[7-8] must be jumpered for an
SRAM device.
Note
SRAM contents are sometimes affected by system noise. Therefore, the
use of SRAM is not recommended in electrically noisy environments,
especially when systems are critical.
The SSD0 socket also supports flash and EPROM devices. By default,
SSD0 reserves 192 KB for the system/video BIOS and 320 KB for a
DOS drive. When an SRAM or flash device is used, the DOS drive is
read/writeable through PICO FA. After PFORMAT has run, the
SETSSD/SSD0BIOS option allows the DOS drives on SSD0 to be the
full size, 512 KB.
WARNING!
Alignment of an SRAM, flash, or EPROM device into SSD0 is
critical. Be certain to properly align pin 1 of either the SRAM,
flash, or EPROM device with pin 1 of SSD0 on the PC-500.
≡ SSD0 replaced with a flash device
Before replacing SSD0 with a flash device, do the following steps:
1. Power off the PC-500 and then make sure W2[5-6] is jumpered in order
to boot from the BIOS on SSD1.
2. Since SSD0 is to be replaced with an unprogrammed device, the PC-500
must be configured to boot from SSD1. Run SETSSD.EXE to change
the boot device:
PC500 C:\> SETSSD SSD1 SSD0
3. Power off the PC-500 and install a 512K flash into SSD0 at socket U21.
Both W5[1-2, 3-4, 5-6, 9-10] and W2[7-8] must be jumpered for a flash
device.
Selecting an SSD BIOS
Each SSD may contain a system BIOS and a video BIOS. To select an
SSD BIOS in SSD1, add jumper W2[5-6]. To use SSD0 BIOS, remove
jumper W2[5-6]. See Table 8-2 for the proper settings. To program the
system BIOS/video BIOS, refer to the Managing SSDs chapter.

SSD0 replaced with an EPROM/OTPROM
1. Follow steps one through three in the SSD0 replaced with a flash device
section and use a 512K flash.
2. Power off the PC-500 and remove the flash from socket U21.
3. Use an off-card programmer to program a 512K EPROM/OTPROM.
Use the flash as the master copy.
4. Insert the programmed EPROM/OTPROM into socket U21.
5. Remove jumper W2[7-8] for EPROM USE.
6. Power on the PC-500.
7. The new SSD0 device is now ready to be used as a bootable, read-only
DOS drive.
≡ SSD1
Generally, SSD1 is meant for storing the application programs to be
executed on powerup. The programs are automatically loaded into DOS
memory and executed. The standard version of the PC-500 comes with
a 2 MB flash soldered on-board, while the optional version contains a
1 MB flash soldered on-board. Your application programs can be saved
to flash using the PICO FA driver which makes the flash device a read/
write disk on your PC-500. Saving your programs onto the read/write
disk allows you to do this up to 100,000 times, allowing updates to your
application programs. These devices are erased automatically during
the programming process.
SSD1 can be accessed directly as a read/write DOS drive with the PICO
FA driver. Also, it can be accessed directly as a read/write DOS drive
when the PICOFA.SYS driver is loaded. While this is convenient for
product development, the flash, however, has a limited number of writes
allowed. Therefore, Octagon does not recommend SSD1 be used as a
data logging device. Refer to the Software utilities appendix for information on supported flash devices and a description of PICO FA.
≡ DRAM
The standard version of the PC-500 is shipped with 1 MB of DRAM
on-card. The PC-500 can also be configured with 16 MB of surface
mounted DRAM. The on-card DRAM socket holds up to a 32 MB dual
in-line memory module (DIMM). The card supports fast page mode
(FPM) or extended data out (EDO) types of memory. These can be
symmetric or asymmetric configurations. You may order EDO DIMM
memory modules from Octagon Systems. These memory modules,
including a 32 MB version, are also available from third party electronic
component distributors. See the following for ordering information:

IRQ routing and opto IRQs
IRQ routing and opto IRQs
≡ Interrupt routing
The PC-500 provides a flexible method of enabling, disabling, and
routing system interrupts via an “in system” programmable logic device.
The logic device not only reduces the number of physical jumpers, but it
also reduces the possibility of choosing the incorrect jumper configuration. For example, upon configuration the electronic jumpers remain set
until they are reprogrammed for a different configuration.
This device also allows some of the PC/104 bus interrupts and some of
the on-board generated interrupts to be routed to other IRQs of the
programmable interrupt controller. This routing matrix requires the
user to run the SETIRQ utility program to update the routing matrix
with the desired IRQ routes.
In addition to IRQ routing, the I/O range select A and select B bits can
be set so that the base addresses in COM5, EZ I/O, and COM3 through
COM5 IRQ status registers can be moved to different locations. These
can also be read at I/O address 0A9h bits 4 and 5.
See also the SETIRQ.DOC file in the \IRQ directory on the PC-500
utility disk for more information. The utility disk contains several ISP
files to program into the matrix. If these are not sufficient, call
Octagon’s Technical Support at 303-426-4521 for new ISP files that may
have become available.
Note
If an output is not routed as a signal, then the output or destination is
neither driven high nor low, but is in a high impedance mode.
Note
When you program a new IRQ routing matrix, the printer port must be
set to bi-directional mode. Also, any field devices connected to the
printer port must be disconnected.

IRQ routing and opto IRQs
≡ Opto IRQs
OPTOA and OPTOB are the two optically isolated channels and are
accessible at J10. These channels are configurable to drive either the
SUSPEND/RESUME or the PMI signal. Also, either OPTOA or OPTOB
can be routed through the interrupt routing matrix to generate a system
reset. The opto-isolation allows the input source to extend as far as
50 feet from the card. A +5V signal activates the SUSPEND/RESUME,
PMI or system reset signal. Noise filtering is built-in and the isolation
from the system ground is 500V. A voltage greater than 3.1V at 5.0 mA
guarantees a SUSPEND/RESUME or a PMI interrupt or a system
reset.
When signaling for SUSPEND/RESUME, PMI, or system reset, the
voltage is applied in a pulse period greater than 50 µS. The interrupt
matrix chip requires that the input voltage remains stable until the
interrupt is acknowledged. At that time, the interrupt source can be
rearmed by returning the input to 0 volts.
Note
See the Accessories appendix for mating information on the OPTOA and
OPTOB connectors.
The interrupt routing matrix provides flexibility to the interrupt structure which allows connection between the lower-ordered ISA interrupts
and the unused higher-ordered interrupts. Caution must be used when
configuring the jumper options.
Note
Bus IRQ6 can be inadvertently routed to two interrupts. This is not an
acceptable configuration. The application software must also be aware
of the interrupt that is set for the particular resource.
≡ Interrupt routing matrix defaults
The 500_001.ISP file lists the interrupt routing matrix defaults. See
the SETIRQ.DOC file on the PC-500 utility disk for more information.

The base I/O address for the EZ I/O port is 330h (default). This address
can be changed through OctaGlue PCS_2 to one of four addresses.
Refer to the section Interrupt routing in the IRQ routing and opto IRQs
chapter to change the base address of the EZ I/O chip.
Based on the I/O range select A and B, you can determine the port
addresses for the EZ I/O port by reading 0A9h bit 4 and 0A9h bit 5.
Refer to Table 11-4.

≡ Configuring and programming the EZ I/O ports
Located at J11 on the PC-500, the digital I/O connector is programmable by an Octagon EZ I/O digital chip. The EZ I/O chip has three
ports with eight parallel I/O lines (bits) per port. This port can use one
of four base I/O addresses. All lines can be individually programmed as
all inputs, all outputs, or individually as inputs or outputs. You can
alter which bits are inputs or outputs by writing a control command to
the control register of the EZ I/O port. When a line is configured as an
output, it can sink a maximum of 15 mA at 0.4V or can source 15 mA at
2.4V. On powerup and software or hardware reset, all digital I/O lines
at J11 reset as inputs.
Programming the EZ I/O
Follow these steps to program the EZ I/O chip:
1. Configure the EZ I/O port bit directions, either as inputs or outputs.
2. Write to port A, B, or C with the desired level or read the bit level from
the desired port.
Configuring the EZ I/O
Follow these steps to configure the EZ I/O chip
1. Write a "2" to the control register (base address + 3). This places
the I/O chip in “direction” mode:
(default base address = 330h)
OUT 333h, 2
(control register, direction mode)
2. Set the direction of each bit. A "0" written to the corresponding line
indicates an input and a "1" bit indicates an output. Each bit corresponds to the equivalent I/O line.

For example, writing 00011100 to port C (base address + 2) will configure port C I/O lines 0, 1, 5, 6, and 7 to be inputs and lines 2, 3, and 4 to
be outputs:
OUT 332h, 1Ch (00011100 binary = 1C hexadecimal)
3. Write a "3" to the control register (base register+3). This places the I/O
chip back into “operation” mode:
OUT 333h, 3
(control register)
Writing and reading from EZ I/O
Writing to or reading from the desired EZ I/O port is accomplished with
single program statements:
1. To write a bit pattern to the desired EZ I/O port:
OUT 332h, FFh
All bits of port C go high; all input bits are unaffected.
2. To read a bit pattern from the desired EZ I/O port:
PORTC = INP(332h)
The byte read from port C is assigned to variable port C.
EZ I/O output program examples
To configure ports A, B, and C as all outputs, issue the commands:

EZ I/O
≡ Opto-module rack interface
You can interface digital I/O lines to an 8-, 16-, or 24-position opto-module
rack. One end of the CMA-26 cable plugs into the EZ I/O connector and the
other plugs into an MPB-8, MPB-16, or an MPB-24 opto rack. Refer to the
MPB opto racks data sheet for more information.
You can also use a CMA-26 cable to connect the EZ I/O port to an STB-26
terminal board and then to the opto rack. The STB-26 has two 26-pin
connectors, one of which would connect to the EZ I/O port, the other would
connect to the opto rack. Refer to the following opto rack diagrams.
For either configuration, run a separate power line to +5V and ground on
the opto-rack.

LED signaling and “beep” codes
≡ Description
The PC-500 has a bicolor LED that is used by the BIOS to signal system status.
Immediately after the PC-500 powers on, both LEDs are lit and display
an amber color. Upon completion of the boot sequence, the amber LED
turns off and the green LED remains on.
If a failure occurs during the boot sequence, visual beep codes are displayed to the LEDs. The visual beep codes are defined in the following
table. Also, if a speaker is installed at J4, the beep codes are audible.
The bicolor LED also indicates memory suspend status. Upon entering
memory suspension, the green LED turns off and the amber LED turns
on. On a resume condition, the amber LED turns off and the green LED
turns on.
When the system enters the cool down clocking state, the green LED
and the amber LED turn on. When the system exits the cool down
clocking state, the amber LED turns off and the green LED
remains on.

≡ Programming the video BIOS
Note
When the SCSI hard drive is used, the SCSI boot BIOS and the video
BIOS both share the C8000-CFFFFh region. For more information on
the region share between these two BIOSes, refer to the Video BIOS
reprogramming section in the SCSI chapter.
The PC-500 is factory configured and programmed for a VGA analog
monitor. If you wish to use a monitor other than the default or a flat
panel display, you must reprogram the video BIOS for the appropriate
display. To reprogram your video BIOS, see the README.DOC on your
65550 utility disk.
If you are using the default monitor and have not previously reprogrammed the video BIOS, please skip to the section Connecting the
monitor/display.
1. Attach a standard VGA monitor, an AT/PS/2 compatible keyboard, and
a floppy drive to the PC-500.
2. Refer to Figure 13-1 for the correct cables and locations of the keyboard,

Watchdog timer and hardware reset
Watchdog timer and hardware reset
≡ Description
The watchdog timer is a fail-safe against program crashes or processor
lockups. It times out every 1.6 seconds (1.6 sec. typical, 1.00 sec. min.,
2.25 sec. max.) unless reset by the software. The watchdog timer can be
controlled through the enhanced INT 17h interface which is a built-in
function on the PC-500.
≡ Enhanced INT 17h function definitions
This section provides definitions for the following functions: Enable
watchdog, Strobe watchdog, and Disable watchdog.

≡ Hardware reset
The PC-500 has a button which allows you to reset the system without
turning off the power. This provides a more complete reset than the
<CTRL><ALT><DEL> method. The RESET command also accomplishes the same thing as the reset button. It is also possible to issue a
hardware reset through the opto-isolated inputs, either OPTOA or
OPTOB channels at J10. See the IRQ routing and opto IRQs chapter
for more information on opto channels. Refer to the component diagram
in the Quick start chapter for the location of the reset button.
WARNING!
When using COM1 as the console, the <CTRL><ALT> <DEL>
commands on the host system keyboard only reset the host
system. Use the RESET command to issue a hardware reset
on the PC-500.

Serial EEPROM and CMOS RAM
Serial EEPROM and CMOS RAM
≡ Description
Up to 768 words of user-definable data can be saved in the serial
EEPROM. The serial EEPROM does not require battery backup to
maintain the data when the system power is off. The serial EEPROM is
easily accessible via software interrupts by most programming
languages.
The calendar/clock provides the user with 128 bytes of user-defined
CMOS RAM. This RAM requires battery backup to maintain data. If a
battery is not desirable, this data can be stored in serial EEPROM,
written to CMOS RAM on powerup, changed and written back to serial
EEPROM.
≡ Enhanced INT 17h function definitions
This section provides definitions for both serial EEPROM and CMOS
RAM functions. The serial EEPROM definitions include the following
functions: Read a single word from serial EEPROM, Write a single word
to serial EEPROM, Read multiple words from serial EEPROM, Write
multiple words to serial EEPROM, and Return serial EEPROM size.
The CMOS RAM definitions include the following functions: Read extended CMOS RAM, Write extended CMOS RAM, Check CMOS battery,
Copy contents of serial EEPROM to extended CMOS RAM, and Copy
contents of extended CMOS RAM to serial EEPROM.

Transferring files/remote disks
Transferring files/remote disks
≡ Transferring files between the PC-500 and your PC
Once you have established communications between your PC and the
PC-500, you can serially download files to any read/write drive used by
the PC-500. You can also upload files from the PC-500 to your desktop
PC for editing and debugging.
There are two methods to download files through the serial port to the
PC-500:
1. The TRANSFER utility is used to download files, one at a time, to the
PC-500 using the XMODEM protocol. TRANSFER.EXE resides on the
PC-500 BIOS drive and on the PC-500 utility disk and is used to send or
receive files via the serial port (e.g., COM1). TRANSFER.EXE uses the
XMODEM protocol, as does PC SmartLINK. (See the note below on
XMODEM).
2. REMDISK/REMSERV utilities allow access to all of the files on a remote disk drive. REMDISK.EXE and REMSERV.EXE are located on
the PC-500 BIOS drive and the PC-500 utility disk. Once these programs are executed, single or multiple files can then be transferred to
and from the PC-500 using DOS COPY or XCOPY commands.
TRANSFER.EXE, REMDISK.EXE and REMSERV.EXE are located on
the PC-500 BIOS drive, in the DOS directory, and on the PC-500 utility
disk in the \DOS directory. Refer to the Software utilities appendix for
more information on these programs.
Note
XMODEM only transfers files in which the file size is exactly on a 128
byte boundary. If the file size does not fall exactly on the boundary,
XMODEM automatically rounds the file size up to the next 128 byte
boundary with padding characters. For example, a file with a size of
10,000 bytes, will be rounded up to 10,112 bytes, transferred, and
written with the new file size. In most cases, this is not a concern, but
in some instances the XMODEM padding causes problems. The padding problems become apparent when an application program is expecting a specific file size or is expecting characters other than the padding
characters to be at the end of the file.

Transferring files/remote disks
PC-500 user’s manual
≡ Transferring files to the PC-500
The following steps detail the procedures for transferring files from your
PC to the virtual drive on the PC-500. In order to transfer files from
your PC to the PC-500, you must execute the TRANSFER program from
both the PC-500 and your PC.
1. Connect a 9-pin serial cable with a null modem adapter between COM1
of your PC to COM1 of the PC-500, using a VTC-20F cable.
2. Execute the TRANSFER program from the PC-500 to receive a file from
your PC.
TRANSFER /COM1 /R /V <drive>filename.ext
<drive> is the drive on the PC-500 where the file will be transferred.
/R specifies to receive a file (default).
filename.ext is the name of the file on the PC-500 which you are
receiving from your PC.
COM1 specifies the serial port on the PC-500.
/V enables “R” characters upon receiving a block and “T” upon transferring a block. Do not use /V when using a serial console.
3. Execute the TRANSFER program from your PC to send a file to the
PC-500. /S specifies send to file.
TRANSFER /COM1 /S /V <drive><path>filename.ext
filename.ext is the name of the file on the PC which you are sending
to the PC-500.
Note
An alternate method of transferring a file is to press <ALT><D>, when
you use PC SmartLINK.
Note
Transfer will time-out if the program has not been started after approximately 40 seconds. It displays the following message:
Failed to receive <drive>filename.ext
Deleting <drive>filename.ext
Also, you may speed up the transfer using the /Bnnnn switch to increase
the baud rate. Example: /B57600. When you use a serial console, do
not use the /B option on the PC-500. Instead, change the serial console
baud rate in SETUP.

Managing SSDs
Managing SSDs
≡ PICO FA flash file system
By default the PICO FA extended BIOS is loaded at system boot. A
message similar to the following is displayed on your screen as the
system boots each PICO FA drive found:
PhoenixBIOS(TM) A486 Version x.xx
Copyright (C) 1985-1994
Phoenix Technologies, Ltd.
The PICO FA extended BIOS allows the PC-500 to boot from the flash
file system on-board the PC-500. These drives are “simulated” hard
drives that look like a standard hard drive on a PC. In some instances
it will be necessary to disable the PICO FA extended BIOS. This is
done by removing jumper W4[3-4]. W4[3-4] works with the D8000DFFFF ROM enable in SETUP. Octagon recommends that you use this
jumper to disable or enable the PICO FA BIOS region and leave the
D8000-DFFF ROMSETSSD enabled in SETUP as the default.
Note
When installing Windows 95 or Windows NT operating system, it is
necessary to disable the PICO FA flash file system.
Phoenix’s PICO FA™ includes an extended BIOS (PICOFA.IMG), a
device driver (PICOFA.SYS), a format utility (PFORMAT.EXE), and a
test utility (TESTRFA.EXE).
Use the device driver PICOFA.SYS to access SSDs when booting from a
floppy or hard drive, when the extended BIOS (PICOFA.IMG) is disabled.
≡ Defining SSDs using SETSSD
The following examples demonstrate how to define SSD drive order:
n To set SSD0 first and SSD1 second, enter the following command:
PC500 C:\> SETSSD SSD0 SSD1
Note
SSD0 is C: and SSD1 is D:. Drive designators will change depending on
the SETSSD settings.
n To set SSD1 first and SSD0 second, enter the following command:
PC500 C:\> SETSSD SSD1 SSD0
20-1
Managing SSDs
PC-500 user’s manual
Note
In the above example SSD1 is C: and SSD0 is D:. Drive designators will
change depending on the SETSSD settings.
n To use only SSD1, enter the following command:
PC500 C:\> SETSSD SSD1
If there are other hard drives on the system, add the /before option to
place the order of the SSDs before the hard drives, or add the /after
option to place the SSDs after the hard drives. For example,
n To set SSD0 as the first drive, SSD1 as the second drive, and an IDE
drive as the third drive, enter the following command:
PC500 C:\> SETSSD SSD0 SSD1 /before
n To set the IDE drive as first in order, SSD1 as second, and SSD0 as
third, enter the following command:
PC500 C:\> SETSSD SSD1 SSD0 /after
In the last example, the IDE drive is C:, SSD1 is D: and SSD0 is E:.
Other drive letter designations may be added by device drivers (such as
VDISK.SYS), which are in the CONFIG.SYS file on the boot drive.
The boot drive is based upon the drive order set by the SETSSD command and by SETUP's “boot sequence” option. If the boot sequence is
set to “A: THEN C:,” the system will look for a floppy diskette in drive
A:. If a diskette is not installed, or a floppy is not defined, the boot drive
will be the first drive specified in the SETSSD command. If the boot
sequence is set to “C: ONLY,” the check for a diskette is bypassed.
Note
The SETSSD parameters may also be overwritten by removing the
USESETUP jumper and resetting the system. If the parameters specified at the PICO FA first/second drive prompt are different from the
previous SETSSD command, and you answered “No” to the “Save”
prompt, the SETSSD output will not be accurate. Therefore, we recommend that you answer “Yes” to the save option to prevent confusion.
Note
After you run SETSSD and the drive order has changed, the new parameters will take effect after a reset.
The drive order affects the number entered at the PFORMAT Hn command. See the Using PFORMAT to format an SSD section in this
chapter.
≡ Using PFORMAT to format an SSD
Formatting SSD1
This section describes how to format SSD1.
20-2
PC-500 user’s manual
Managing SSDs
WARNING!
Reformatting SSD1 requires the use of a floppy or a hard
disk to restore system files.
1. Define the SSD order with the SETSSD command. Since the command
input varies depending upon the parameters you need to enter, see the
SETSSD command in the Software utilities appendix.
2. To begin formatting SSD1, execute PFORMAT as follows:
PC500 C:\> PFORMAT Hn
where n is the hard drive sequence number. This number includes IDE
drives and SSDs.
For example, if you have 0 IDE drives and SETSSD shows:
[HDDs] SSD0 SSD1
then enter:
PC500 C:\> PFORMAT H1
On the other hand, if you have 1 IDE drive, enter:
PC500 C:\> PFORMAT H2
Note
If the drive had not been formatted previously, reset the system before
accessing the drive. This allows DOS to recognize the drive and add a
letter designation to it.
Note
PFORMAT.EXE must be downloaded from the PC-500 utility disk. This
file is located in the \UTILS directory.
Note
PFORMAT.EXE will not format IDE/ATA drives.
≡ Using SYS to make an SSD bootable
Adding operating system startup files (using SYS)
To add the system files, issue the following operating systems command:
C:\> SYS d:
where d: specifies the drive letter.
For example, if your system has 1 IDE drive, and SETSSD shows
“[HDDs] SSD0 SSD1,” then SSD1 should be drive E:. To SYS this drive,
use the “SYS d:” command.
Note
SYS.COM must be downloaded from the PC-500 utility disk. This file is
located in the \DOS directory.
20-3
Managing SSDs
PC-500 user’s manual
Note
If you are adding the MS-DOS operating system to SSD1, you must first
boot from an MS-DOS bootable device (floppy or hard drive).
Note
If you are not booting from ROM-DOS, and wish to SYS ROM-DOS back
to the drive, the SYS command requires you to issue the following ROMDOS commands: COMMAND.COM, ROM-DOS.SYS and SYS.COM.
≡ Changing boot SSD
Autoexecuting your application
This section describes how to autoexecute your application.
1. To autoexecute your application in SSD1, use the SETSSD command to
define your SSD as the boot device. Since you need to define the order
of SSD1 as the first of the SSDs (and before any IDE drives), enter the
following command:
PC500 C:\>SETSSD SSD1 SSD0 /before
2. Add your application to SSD1, and modify the AUTOEXEC.BAT program to include your application.
3. Reset the system. SSD1 is now drive C: and your application should
begin execution.
Note
If the SETUP option “Boot Sequence” is set to “A: THEN C:”, remove
any floppy in drive A: before resetting the system.
Note
The SETSSD options are not used when W2[9-10] is not jumpered.
≡ Using SETSSD and TESTRFA to test an SSD
To test SSD0 and SSD1 (i.e., destroying all drive data on the SSD1),
follow the steps below:
1. Run SETSSD.EXE to determine which socket to use with TESTRFA.
The socket (either 0 or 1) depends on the order of the SSDs. The first
SETSSD’ SSD is socket 0 and the second SSD is socket 1. To configure
the order of the SSDs, see the Defining SSDs using SETSSD section in
this chapter.
For example, running SETSSD with no parameters may give the following output:
PC500 C:> SETSSD
[FDDs] SSD1 SSD0 [HDDs]
20-4
PC-500 user’s manual
Managing SSDs
In the above example, SSD1 is the first SSD which means TESTRFA is
socket 0, and SSD0 is the second SSD which means TESTRFA is
socket 1.
2. Execute TESTRFA /Sn where n is the socket determined in step 1. For
SSD0 in the above example, enter:
TESTRFA
/S1 /E
For SSD1 in the above example, enter:
TESTRFA
/S0 /E

CPU power management
CPU power management
≡ Description
The power demands of a system can severely limit an application due to
thermal constraints or the raw power usage in a battery-operated
application. In order to maintain speed and efficiency, a softwarecontrolled, power management system must be tailored to the application. Even if your application is operating within specified limits, a
power management system may improve the life and reliability of your
system by reducing thermal stress to the CPU.
The advance power management functions include:
n SUSPEND/RESUME operation via SMI input and software
n Slowing down the CPU by dividing the clock
n Contextual Save to Disk
Power management can be enabled in the PC-500 SETUP program and
is adjusted with the PMISETUP program. DOS-supplied advanced
power management (APM) programs, such as POWER.EXE are also
supported. See the PC-500 utility disk for a list of example programs
located in the \EXAMPLES directory. For more information on using
the SETUP utility, refer to the SETUP programs chapter. For more
information on using the PMISETUP utility, see the PMISETUP
section later in this chapter.
≡ Power management overview
Power management is implemented via the software management
interface (SMI) function, and provides multiple levels of management.
The firmware is also capable of cooperative power management with an
APM compatible driver or application, such as POWER.EXE. Cooperative power management allows power aware applications to control the
power state of the system without depending on interrupts or device
access to indicate that the CPU is actively executing application code.
At the hardware level, the power management system cannot detect
CPU activity except by monitoring bus activity such as interrupts or
access to specific memory or I/O address ranges.
The hardware is capable of minimal levels of power management without interacting with the firmware at all. Once configured by the firmware, the DOZE timer and the CPU activity monitor (cool-down clocking
mechanism) can slow the system clock to reduce power consumption.
The DOZE timer monitors specific bus activity and reduces the system
clock after periods of inactivity. The CDC mechanism simply guarantees that the CPU spends some specified portion of time at a reduced
clock speed, either due to DOZE mode of firmware controlled reduced
clock mode, or by forcing cool-down periods if neither of these occur.
22-1
CPU power management
PC-500 user’s manual
In a stand-alone environment (no APM software active), the firmware
works in conjunction with the hardware timers and monitoring functions to identify periods when certain devices or the entire system are
inactive. Individual timers are supported for specific devices, including
the hard disk, floppy disk and serial ports. Whenever these devices are
not accessed for a specified period, they are powered down to reduce
system power consumption. Whenever none of the monitored system
devices has been accessed for a specified period of time, the performance
of the system is reduced or the system is stopped altogether to further
reduce power consumption.
In a cooperative environment, devices are still controlled by the firmware, but the CPU is never slowed or stopped without the consent of the
APM software. Rather, the firmware notifies the software when a timer
has expired or some other event has occurred which should place the
system in a reduced power mode. The APM software polls the firmware
for such events. Once an event has occurred, the software initiates the
reduced power mode by acknowledging the event back to the firmware.
The firmware then initiates the reduced power mode. The APM software can inquire “APM aware” applications to ensure that the reduced
power mode is acceptable.
≡ Hardware controlled modes
The firmware assumes that keyboard, disk, and video access should
prevent the system from entering DOZE mode. In addition, specific
interrupts can be configured to reset the DOZE timer. DOZE mode is
typically a reduced clock operation, but a stopped-clock mode is also
supported. If the slow-clock mode is selected, the CPU clock is slowed
from 33 MHz to 8 MHz. If stopped-clock mode is selected, the secondary
DOZE timer is configured to restart the CPU clock whenever the timer
interrupt occurs. This allows the CPU to maintain the system clock
while in stopped-clock mode even though the CPU clock remains
stopped for more than 90% of the time.
The CPU activity monitor (cool-down clocking mechanism) is intended to
prevent thermal run-away in low airflow environments. It essentially
counts the time that the CPU operates in full-speed mode and the time
spent in reduced clock mode. If full-speed mode is maintained for a
period of time that could cause excessive heat build-up, then the clock is
reduced for a cool-down period to maintain an equilibrium level. The
CPU clock is shifted from 33 MHz to 16.5 MHz for a pre-determined
amount of time, back to 33 MHz, and then the CDC cycle begins again.
≡ Device power management
The hard disk, floppy disk, and serial ports are power managed on an
individual basis. For each device, the firmware configures a hardware
timer that is reset each time the device is accessed. When the device
goes unaccessed for the duration of the timer, an SMI is generated to
notify the firmware that the device is inactive. The firmware can then
SUSPEND that device.
22-2
PC-500 user’s manual
CPU power management
Before a device is SUSPENDed, or powered down, its context is saved in
memory so that it can be restored to its active state when it is powered
up. The timer is disabled on SUSPEND to prevent repetitive triggering,
and the chipset is configured to generate another SMI when the device
is accessed again. That SMI allows the firmware to restore power to the
device and restore its context.
After the device power is restored by a triggering event, such as a
keyboard stroke, the access SMI is disabled and the timer is restarted.
This cycle may then be repeated. The status of each device is maintained to ensure that a powered-down device is not accessed for powerdown repeatedly.
Devices other than the disks and serial ports are not monitored for
activity, but can be individually powered down in reduced power states
at the system level.
≡ System power management
At the system level, power management is very similar to the device
level management, with a couple of exceptions. Cooperative management is supported, allowing an APM driver, such as POWER.EXE, to
control the actual power state transitions. This is done by identifying
power management events and reporting them to the APM driver via a
polling mechanism. Power state transitions then occur at the request of
the APM driver. Individual device states in the various system power
states can be configured via CMOS locations to the extent at which the
firmware has the ability to control them. For example, the video can
remain ON during STANDBY, which makes STANDBY mode more
transparent to the user, or it can be powered OFF during STANDBY to
further reduce power. The parallel port may be powered OFF in
STANDBY, or remain ON in STANDBY and powered OFF in SUSPEND, but on return to full speed it must be powered ON because there
is no access SMI available. The disks and serial ports, on the other
hand, may remain powered OFF after the system RESUMEs and can be
powered ON when accessed.
The IDLE timer can be reset by numerous sources, including device
accesses and interrupts. Note that it is possible for the IDLE timer
configuration to be of shorter duration than the device timers. This
means that the system can be deemed IDLE even though some of the
devices are still active. When this occurs, the device power states are
set according to their configuration in CMOS.
Note that the APM interface prevents the system from entering
STANDBY or SUSPEND modes directly. These modes will be entered,
but that will occur through the APM interface (INT 15h) at the request
of the APM driver.
SUSPEND mode is the lowest power state that the system can attain
while still powered. The CPU clock is stopped and all controllable
devices are powered down. Because the devices are powered down and
the CPU is not running, only an external event can cause the system to
22-3
CPU power management
PC-500 user’s manual
RESUME normal operation. These events include the SUSPEND/
RESUME input (J10[3-4], OPTOB), the COM2 RI signal (Ring Indicator),
and interrupts from selected sources located in the .PMI file. The devices
which are powered ON when the system RESUMEs are specified in
CMOS, loaded from the .PMI file. Devices which do not have associated
access SMIs, must be powered up. In addition, since the CPU was stopped,
the system time must be updated. If an APM driver is operating, it has
the responsibility of updating the time when notified to do so. Otherwise,
the firmware will update the DOS compatible system time if configured to
do so. For operating systems with DOS compatible system clocks, this
function should be disabled in CMOS. Since the clock does not run in
SUSPEND mode and the system is not restarted by IRQ0 to maintain the
time of day, the time must be reset when the system resumes. Normally,
the BIOS can read the actual time from the real time clock and restore the
operating system’s timer from that value. However, some operating systems do not support the update methods utilized by the BIOS for this
function. The time update can be enabled or disabled using the PC-500
SETUP program. In SETUP, the following options are available:
Power Management:
DOZE Clock (Slow, Stop):

IRQs chapter for the EPMI connection and signal requirements.
7. The PC-500 system enters the SUSPEND mode, powering down any
devices that can be powered down.
8. A system RESUME is generated by any event defined in the .PMI file or
the when an external RESUME signal is applied at J10[3-4]. If a VGA
monitor is attached, the video will return. If a hard drive is attached,
the drive will not spin up until accessed.
Note
The default signals at J10 are [1-2] PMI and [3-4] SUSPEND/RESUME.
These signals may be changed by reprogramming the IRQ matrix. See

CPU power management
PC-500 user’s manual
Refer to the default .PMI file in the Power management configuration
section in this chapter for all of the power management options.
STANDBY mode is similar to hardware DOZE mode, except that it is
firmware controlled and devices may be power managed as well as the
CPU clock. STANDBY is controlled by software, such as POWER.EXE.
Since the CPU may still be executing in STANDBY mode, access events
may RESUME the system in addition to external inputs, such as interrupts. The firmware must configure the chipset to report these events to
the firmware via an SMI. This allows the hardware to restore the CPU
clock while notifying the firmware to restore power to the managed devices. On RESUME from STANDBY mode, all devices which cannot
generate an access SMI are powered up and those which can generate an
access SMI are powered up if specified in CMOS. Any device access or
specified interrupt can cause the system to RESUME.
How to initiate the STANDBY option
1. In the PC-500 SETUP and in a .PMI file, enable power management and
select the following options:

Set the time delay, in minutes, for the “standby-delay” option and devices
to be powered down, such as drives and serial ports.
Note
The hard drive and floppy drives are actually controlled by firmware and

5. Initiate APM software, such as POWER.EXE.
6. The PC-500 system enters the SUSPEND mode as determined by the
APM software, powering down any devices that can be powered down.
7. A system RESUME is generated by any event defined in the .PMI file or
when an external RESUME signal is applied. If a VGA monitor is
attached, the video will return. If a hard drive is attached, the drive
will not spin up until accessed.
Refer to the default .PMI file in the Power management configuration
section in this chapter for all of the power management options.
≡ Save to disk
The firmware provides an additional SUSPEND mode which supports
removal of system power. This mode is initiated through software or by
the external power management input. In this mode, the context of the
entire system is saved on the hard disk so that it can be restored completely when power is restored to the system. The system context
includes all of the system memory, video memory, and the states of the
hardware registers in all devices (interrupt controllers, DMA controllers,
serial ports, keyboard controller, etc.). The firmware can only save and
restore devices of which it is “aware”, meaning those that are on-board
and most standard VGA video controllers. This function may not be
22-7
CPU power management
PC-500 user’s manual
fully functional for some extended system configurations. This function
will only work with a hard drive and not with the on-board SSD flash
drive or with a flash drive card.
After a Save To Disk function has been completed, the system must be
reset to restore the context. After saving the context of the system to
disk, all devices are powered down and the CPU is SUSPENDed. The
validity of the system context on the hard disk is identified by marking
a bit in the configuration EEPROM. On the next system reset, the
validity of the context is checked in EEPROM and, if valid, is restored to
the system memory and devices.
In order for the Save to Disk function to execute, the hard disk must be
prepared using the PHDISK.EXE program. A special partition is saved
on the disk which must be big enough to hold the system context. Generally speaking, this means the size of the installed system memory
(typically 1 to 17 MB DRAM) plus the size of the video memory (typically 512 KB to 1 MB). However, a larger partition may be created in
order to support additional system memory to be added at a later time.
WARNING!
PHDISK.EXE provides the same function as FDISK but also
creates a special partition for the Save to Disk option. Only
use a hard drive which any existing data can be destroyed.
The Save To Disk function may be disabled. If it is disabled, then the
power management firmware will, upon detection of the external PMI
signal (J10[3-4]), execute an interrupt 15h with register AX set to
0AA55h and register DX set to 1234h. This indicates a power down
request when the PMI input signal is generated. PFHINT15.EXE is a
sample TSR that prints “PFH” to the screen when the PMI signal is
generated but the “save to disk” option is disabled. The
PFHINT15.EXE and PFHINT15.CPP files are located in the
\EXAMPLES directory on the PC-500 utility disk.
How to initiate the save to disk option
1. Use PHDISK.EXE, located in the \UTILS directory on the PC-500
utility disk, to prepare the hard drive.
2. In PC-500 SETUP and in a .PMI file, enable power management and
select the following options:

3. Load the .PMI file changes by including the .PMI file on the PMISETUP
command line. PMISETUP is located in the \UTILS directory:
PC500 C:\> PMISETUP TEST.PMI
4. Hardware reset the system for the PMISETUP options to take effect.
The PC-500 system is now ready to Save to Disk.
5. Initiate a PMI input signal at J10[1-2]. Refer to the IRQ routing and
opto IRQs chapter for the PMI connection and signal generation.
Note The default signals at J10 are [1-2] PMI and [3-4] SUSPEND/RESUME
signal. These signals may be changed by reprogramming the IRQ matrix. See the IRQ routing and opto irqs chapter for more information on
the IRQ matrix.
6. The system now performs a contextual save, saving all relevant information to the special disk partition.
7. The system will respond with “Please turn off your computer.” Power
down the system. The CPU enters SUSPEND mode. The validity of the
system context on the hard disk is identified by marking a bit in the
configuration EEPROM.
8. When the system is powered on, the validity of the context is checked in
EEPROM. If valid, the system’s context is restored to the system
memory and devices, back to where it was before the PMI signal was
generated.
≡ Power management configuration
The power management functions can be globally enabled or disabled in
CMOS. The PC-500 SETUP.EXE and PMISETUP.EXE utilities provide
an option for enabling or disabling power management.
Enabling power management
Whichever utility, SETUP or PMISETUP, is configured and saved (or
loaded) last, that configuration is used for enabling or disabling power
management. In other words, if the power management option is disabled in SETUP and then later a .PMI file which shows pmi-enable = Y is
loaded with PMISETUP, the power management option in SETUP will
now show power management as being enabled.
In PC-500 SETUP, the following options are available:
Power Management:
DOZE Clock (Slow, Stop):
Time Updated After Suspend:
ENABLED or DISABLED

System timers
The system timers define the delays associated with power state transitions in the system. Three managed system power modes (in addition to
full on) are supported, DOZE, STANDBY, and SUSPEND. Individual
timers for system devices, including floppy disk, hard disk, and serial ports
are also provided. The timers are described below:
In a .PMI file, the following options are available:
fdd-to=xx
Sets the on-card (LPT1) floppy disk drive time-out
value (x=0-31 minutes)
hdd-to=xx
Sets the hard drive time-out value (x=0-31 minutes)
COM1-to=xx
Sets the COM1 time-out value (x=0-31 minutes)
COM2-to=xx
Sets the COM2 time-out value (x=0-31 minutes)
doze-delay=x
Sets DOZE time-out before STANDBY(x=0,2,8 seconds)
standby-delay=xx Sets delay time before STANDBY (x=0-31 minutes)
suspend-delay=xx Sets delay time before SUSPEND (x=0-31 minutes)
Doze timer enable and resets
The DOZE mode may be selected to be a SLOW clock or STOP clock mode
and is determined in power management SETUP. Numerous sources may
reset the DOZE timer, preventing entry to DOZE mode. The BIOS assumes that video, floppy, hard disk, and keyboard accesses should all reset
the DOZE timer. In addition, various interrupts can be configured to reset
the timer. DOZE timer 0 is used for all DOZE reset selections. DOZE
timer 1 is used for the special case of the timer interrupt in a STOP clock
mode. In this mode, DOZE timer 1 is configured for a 4 millisecond timeout, with only IRQ0 configured to reset DOZE timer 1. This allows the
CPU to resume normal operation for 4 mS on each IRQ0 in order to maintain the time of day.
In the PC-500 SETUP, the following options are available:

IDLE timer resets
The IDLE timer monitors system activity to prevent the system from
entering STANDBY or SUSPEND modes if bus activity indicates that
the system is busy. Access to these devices will also cause the system to
RESUME from STANDBY mode. The bus activities that are monitored
are configured in a .PMI file:
EPMI-reset-idle=Y/N
LCD-reset-idle=Y/N
COM1-reset-idle=Y/N
COM2-reset-idle=Y/N

Interrupts in the system can also reset the IDLE timer to prevent entry
into reduced power modes. These interrupts should be enabled to reset
the IDLE timer if they indicate that the system is active. The interrupts to reset the IDLE timer are configured in a .PMI file:

The events which can resume the system from STANDBY mode to full
power can also be selected. Access to the primary devices can resume the
system if access to those devices are selected to reset the IDLE timer. In
addition, interrupts can be selected to resume the system from STANDBY
mode. The interrupts to resume from STANDBY are configured in a .PMI

When the system resumes from STANDBY mode, the CPU clock is restored
to full speed. In addition, some or all of the devices are restored to full
power. The video (if suspended in STANDBY mode) and parallel port, are
always powered up. The following devices may be held in SUSPEND until
they are accessed:
n COM1
n COM2
n On-board floppy disk (LPT1 port)
n Hard disk

PC-500 user’s manual
CPU power management
RESUME from SUSPEND
SUSPEND mode is the lowest power mode supported by power management. In this mode all devices are powered down and the CPU is placed in
SUSPEND mode and the clock is stopped. In addition to the SUSPEND/
RESUME input, the activities that may resume the system from SUSPEND mode can be selected in the .PMI file.
The Ring Indicator from COM2 can RESUME the system after a specified
number of transitions. This function may be enabled and the number of
transitions specified in the .PMI file.
RI-resume-reset=Y/N
Enables RESUME if RI occurs (COM2
ring indicator)
RI-transitions=n
Specifies number of RI transitions (n) for

The EPMI (External PMI OPTOA, J10[1-2]) input can also cause the
system to RESUME. This function is enabled in the .PMI file.
EPMI-resume-reset=Y/N Enables RESUME timer if EPMI occurs
Finally, interrupts may cause the system to RESUME. This is particularly
useful for activities such as a key on the keyboard being pressed. If any
interrupt is to cause the system to RESUME, then the interrupt must be
selected in the .PMI file.

Remote suspend/resume inputs
The PC-500 provides a remote suspend/resume input. The opto-isolated
input is located at J10[3-4]. The opto requires a 5V input pulse and then
triggers a “suspend” or “resume from suspend” on the trailing edge of the
pulse. The minimum pulse width for a 5V pulse is 50 µS in order to signal
either suspend or resume.
If the required options are selected in PMISETUP.EXE, other devices, such
as the input from a serial port or the ring indicator from a modem connected to COM2, will cause the PC-500 to resume.

External PMI interrupt
In case of a power failure, the power management code is capable of
properly resetting the system, saving the state of the system to disk, or
generating an INT 15h. The power failure is signaled by activation of
the external power management input, J10[1-2]. Once activated, the
system either performs a System Reset, performs a Save to Disk operation, or generates an INT 15h. These functions are enabled in a .PMI
file.

Automatic thermal management of the CPU is provided by measuring
the full speed operation of the CPU verses a thermal equilibrium value.
During thermal management, CPU activity is monitored and the activity is considered against other criteria. When determined that the
activity level has exceeded a certain level, the CPU speed is divided in
half from 33 MHz to 16.5 MHz for about 30 seconds, the CPU speed is
increased to 33 MHz and the thermal management cycle begins again.
If thermal management is disabled, the CPU will run “full on” without
any intervention from the firmware. Default configuration from Octagon has thermal management enabled.
WARNING!
Due to the heat generated the 586 processor, it is highly
recommended that thermal management is always enabled
and the CPU not run in “full on” condition. If thermal management is enabled and DOZE is enabled, the PC-500 will
operate to the published temperature specifications. If
thermal management is disabled, care must be taken not to
damage or shorten the life of the CPU. Adequate ventilation,
preferably with a fan and ample room around the CPU and
card cage must be provided. Please contact Octagon Technical Support if the thermal management is to be disabled to
discuss your situation.
The option for thermal management is in a .PMI file:
thermal-management=Y/N

Bitblt engine
W2[3-4] toggles the CPU clock speed between 120 and 133 MHz. When
pins 3 and 4 are jumpered, the CPU clock speed operates at 133 MHz.
When pins 3 and 4 are not jumpered, then the CPU clock speed operates
at 120 MHz.
W2[3-4] optimizes the PC-500’s temperature performance when the
CPU is operating in accelerated GUI environment. When power management is enabled, you must remove W2[3-4] to use the video accelerator. This ensures that the PC-500’s operating temperature is between
–40° and +70° C.

PC-500 user’s manual
However, if power consumption is not a major concern for your system
when using the video accelerator function, Octagon Systems strongly
recommends that you disable power management and install W2[3-4].
This enables the CPU to operate at full clock speed (133 MHz) and still
maintains the PC-500’s temperature performance range between
–40° and +70° C.

≡ PMISETUP
The PMISETUP program allows modification of the 82C465 registers
and optionally the serial EEPROM data associated with the 82C465/
CMOS registers. The command line format for the PMISETUP program
is as follows:
PMISETUP inputfilename [/SHOWALL] [/DEFAULT] [/P] [/?]
PMISETUP will parse a file using KEYWORD=nn[type] options. One
keyword can be specified per line, characters after a semicolon “;” will be
regarded as comments. Blank lines are ignored. If multiple lines contain
the same keyword, the last value will be used. Keywords and values are
not case sensitive.
A sample input file, TEST.PMI, is as follows:
pmi-enable=Y
Disables/enables the power management code
doze-delay=2
Sets DOZE time-out to 2 seconds before standby
hdd-to=10
Sets the hard drive time-out to 10 minutes.
Load the .PMI file changes by including the .PMI file on the PMISETUP
command line. PMISETUP is located in the \UTILS directory:
PC500 C:\> PMISETUP TEST.PMI
The output from PMISETUP will show all selectable options and their
current values even when not specified when the /SHOWALL option is
used.
When the /DEFAULT option is used, default settings are first loaded
before the keywords are parsed. Refer to the default PMI configuration
later in this chapter.
22-16
PC-500 user’s manual
CPU power management
When the /P option is used with the /SHOWALL, the display pauses between each displayed page of information.
When the /? option is used, all other options are ignored and a “help display”
is presented to the user. A <CR> keystroke between each page is necessary
to continue to the next page of help.
If an error occurs during parsing, the line in question will be displayed and
an ERRORLEVEL returned. For example:
>> Parameter out of range error. Line follows:
hdd-to=50
The correct range is 0-31 minutes
or
>> Unknown keyword error in input file line 7. Line follows:
standbuy-delay=10
Standby was spelled incorrectly.
The following ERRORLEVELs will be returned:
0 — No errors occurred.
1 — Unable to save to serial EEPROM.
2 — Configuration file not found.
3 — Parsing error or out of range error.
In PMISETUP, the following options are available and can be included in a
.PMI file which is loaded by PMISETUP.EXE. PMISETUP.EXE is located
in the \UTILS directory:
The following are the keywords which are used. To disable options, either
an “N” or “0” is used, depending on the option.

Troubleshooting
Troubleshooting
If your system is not working properly, check the following items:
No screen activity – checking console serial communications
If you do not get the sign-on message after bootup:
1. Make sure all PC/104 expansion cards are removed from the PC-500.
This ensures that other cards are not interacting with the PC-500.
2. Change W2[1-2]/W4[1-2]. Depending upon your current ROM enable
and jumper state, these jumpers disable the video section. See the
Console devices chapter for further instructions on how to enable/disable
the video BIOS device.
3. The VTC-20F serial cable turns the PC-500 serial port into a 9-pin AT
serial port. Make sure a null modem adapter is installed on the other
end, and that the assembly is inserted into the proper serial port on the
PC. Make sure the VTC-20F serial cable is connected to J13 of the
PC-500.
4. Make sure your power module provides +5V (+/-0.25V) and at least 2.5A
of current.
5. After verifying the above conditions, you can monitor voltage levels by
connecting an oscilloscope between the TxD* line on J13 (pin 5) and
ground. After powerup, you should see a burst of activity on the oscilloscope screen. The voltage level should switch between +/-8V. This test
verifies that the CPU is active and that the transmit from COM1 is
functional.
Garbled serial console screen activity
If you do get activity on your console screen but the message is garbled,
check the following:
1. Remove USESETUP W2[9-10] to force 9600, N, 8, 1 for COM1.
2. If you are using PC SmartLINK, make sure you have configured the
software for 9600 baud and have selected the correct serial port for
communicating with your PC. Refer to the PC SmartLINK manual for
information on selecting the baud rate.
3. If you are using communications software other than PC SmartLINK,
Octagon cannot guarantee the operation. Make sure that the software
parameters are set to match those of the PC-500: 9600 baud, 8 bits, 1
stop bit, no parity.

Troubleshooting
PC-500 user’s manual
System generates a BIOS message but locks up when booting from SSD1
1. Remove W2[9-10] and reboot. When PICO FA prompts you, select
SSD1 as the first drive and second drive.
2. Display the directory of SSD1 and verify that all the necessary boot files
exist. Copy any missing files to SSD1.
3. If no files are missing, remake SSD1 to overwrite any files which may
have become corrupted. In addition, you may want to do a PFORMAT
and SYS to SSD1.
4. If SSD1 does not boot, install a floppy in the system, reboot from it, and
remake SSD1.
PICO FA reports a drive, but issuing a DIR generates an
error message
1. The SSD may not be formatted. Run either of the following:
PFORMAT Hn
or
PFORMAT Hn /m
where n represents the hard drive number.
For more information, see the on Save and run programs chapter.
PICO FA does not report the drive
1. Run SETSSD and make sure it is correct.
2. Make sure that W4[3-4] is jumpered or that PICOFA.SYS is in your
CONFIG.SYS file of your floppy hard drive.
3. Install a jumper on W2[9-10].
4. Reboot your system.
System will not recognize hard drive
1. Run SETUP and confirm that on-board IDE interface is enabled.
2. Try changing Primary Master Fixed Disk to User and specify Heads,
Sectors, and Cylinders.
3. Check hard drive Master/Slave jumpers.

Troubleshooting
System locks up after powerdown/powerup
If the power supply does not drain below 0.7V, the CMOS components
on the card will act like diodes and forward bias. This is typically
caused by using power supplies that have large output capacitors.
Either use a different power supply that discharges faster, leave the
power off until the supply has adequate time to discharge or place a
100 ohm, large wattage resistor across the output capacitor.
≡ Technical assistance
Carefully recheck your system before calling Technical Support. Run as
many tests as possible; the more information you can provide, the easier
it will be for the Technical Support staff to help you solve the problem.

≡ Tie wrap holes
Additional .125" mounting holes are on the PC-500 board for the use of
.100" wide nylon tie wraps. These tie wraps loop around the SSD0 DIP
device and also the DIMM memory expansion device. This feature will
increase the ruggedness and the retention ability in high vibration
environments. Nylon tie wraps are available from a hardware specialty
supplier such as Richco, phone number: 1-800-621-1892. The following
letters specify the length of the tie wrap:
L=5.75", V=8.00", X=18.00"

≡ GETBIOS.EXE
Purpose
This support command stores the BIOS information in a specific file.
Syntax
GETBIOS SSDx filename
Parameters
n SSDx specifies the target SSD that stores the BIOS. The variable x
represents a value from 0 to 1.
n filename specifies the output file for saving or programming.
≡ GETIMG.EXE
Purpose 1
This support command captures an image of an SSD and places it into a
local file.
Syntax 1
GETIMG SSDx filename
Purpose 2
This support command captures an image of an SSD and transfers it to
a host PC running GETIMGH.
Syntax 2
GETIMG SSDx /COMx [/Bxx] [/Ixx]
Purpose 3
This support command captures an image of an SSD and transfers it to
a host PC running GETIMGH. A non-standard serial port I/O address
is used and the IRQ value must be specified.
B-2
PC-500 user’s manual
Software utilities
Syntax 3
GETIMG SSDx /Uxxxx [/Bxx] [/Ixx]
Parameters
n SSDx specifies the target SSD for file saving or programming. The
variable x represents a value from 0 to 1.
n filename specifies the output file for saving or programming.
n /COMx specifies the PC COM port for serial transfer where x represents a value from 1 to 4.
n /Uxxxx specifies the UART base address to use for serial transfer.
The base address, 100-3FF, is in hexadecimal format.
n /Bxx specifies baud rate of transfer where xx can be (300, 1200,
2400, 4800, 9600, 19200, 38400, 57600, 115 (115200)). The default
is 38400 when using a /COMx switch.
n /Ixx specifies the interrupt to which the UART is connected. The
value x represents a variable from 3 to 15.
Remarks
GETIMG compatibility:
The following devices share the same image and can be used interchangeably: Atmel’s AT29C040 and AT29C040A; SST’s 28SF040; 512K
EPROM; and 512K SRAM. Use an EPROM to make the drive readonly.
Because the AMD 512K, 1MB, and 2MB have a different structure, they
cannot be used in any other type of device. An image from a 512K AMD
flash can only be used on other 512K AMD flashes.
≡ GETIMGH.EXE
Purpose 1
This support command transfers an SSD image from a target PC running GETIMG and saves the image to a host file.
Syntax 1
GETIMGH filename /COMx [Bxx] [/Ixx]
B-3
Software utilities
PC-500 user’s manual
Purpose 2
This support command transfers an SSD image from a target PC running GETIMG and saves the image to a host file via a serial UART
connection. A non-standard serial port address is used and the IRQ
value must be specified.
Syntax 2
GETIMGH filename /Uxxx [/Bxx] /Ixx
Parameters
n filename specifies the output file for saving or programming and it
also represents the host filename.
n /COMx specifies the PC COM port for serial transfer. The variable x
represents a value from 1 to 4.
n /Uxxx specifies the UART base address to use for serial transfer.
The base address, 100-3FF, is in hexadecimal format.
n /Bxx specifies baud rate of transfer where xx can be (300, 1200,
2400, 4800, 9600, 19200, 38400, 57600, 115 (115200)). The default
is 38400 when using a /COMx switch. If COM1 is the console, the
baud rate defaults to the current console baud rate.
n /Ixx specifies the interrupt to which the UART. The variable x
represents a value from 3 to 15.
See also
GETIMG.EXE for details on image compatibility.
≡ HIMEM.SYS
Purpose
This device driver manages extended memory and the high memory
Area (HMA) in a 286, 386, or greater PS/2 system. HIMEM prevents
programs from simultaneously using the same area of memory for two
different purposes. HIMEM supports the eXtended Memory Specification (XMS) 2.0. HIMEM is installed as a device driver in CONFIG.SYS.

The HIMEM driver can be used to allow ROM-DOS to run in High
Memory.
HIMEM supports a default of 32 handles.
HIMEM should not be used with older versions of VDISK. Current
versions of VDISK will use XMS memory if it is available.
HIMEM recognizes PS/2 style machines A20 line control. HIMEM
determines whether to use the PS/2 A20 control or the AT A20 control
method automatically by calling INT 15h, function C0h (get system
configuration).
The automatic detection can be overridden with the "/Machine:n" command line switch. Replacing "n" with 1 designates the PC AT A20
control method. Replacing "n" with 2 designates the PS/2 method.
Example 1
DEVICE=HIMEM.SYS
The above command installs the XMS device driver. Once this driver is
installed, accessing the HMA and Extended Memory (XMS) areas are
legal. The Extended Memory area can contain up to 2 Gigabytes of
memory. Typical systems have 4, 8, or 16 MB XMS memory installed.
Example 2
DEVICE=HIMEM.SYS /machine:1
This example forces the use of the AT style A20 line control.
The HIMEM driver will fail to load if either the machine does not have
memory above the 1 MB boundary or the BIOS does not provide support
for it. It will also fail to load if another XMS manager has been installed previously.
≡ I17HNDLR.EXE
Purpose
This support command allows the system to use the INT 17 functions
when the extended BIOS area is disabled (i.e., W2[9-10] is not jumpered) or when it is reprogrammed with another BIOS.

I17HNDLR
Remarks
This command is used if the extended BIOS area (D800h-DFFFh) is not
used. The I17HNDLR allows the system to use the INT 17 functions.
≡ LCDBIAS.EXE
Purpose
This support command adjusts the LCD bias voltage to obtain the best
contrast for the LCD flat panel. The LCD TSR (Terminate and Stay
Resident) works in combination with the INT 17 extended BIOS/TSR.
Press <CTRL><+> to increase the voltage <CTRL><-> to decrease the
voltage. These keystrokes adjust the voltage within the PC-500’s predefined voltage range (factory default is +22V to +30V). The <-> and
<+> are on the 101 “key enhanced” numeric keypad. The <-> and <+>
are also on the local keyboard as well as the <CTRL> keystroke.
Syntax
LCDBIAS [/D] [/R] [/U]
Parameters
n /D shows a display of “<” or “>” when the LCDBIAS TSR detects a
<CTRL><-> or <CTRL><+>. This display may interfere with graphics based programs.
n /R reinstalls the TSR when detection occurs of a previous TSR copy
of the LCD bias.
n /U uninstalls the TSR. /U only removes the vectors and not the
memory usage of the TSR. TSRs must be removed in the order of
last installed, first removed.
Example 1
To install the LCDBIAS TSR and its display after the LCD bias voltage
has been adjusted, enter the following command:
LCDBIAS /D

≡ PGMVIDEO.EXE
Purpose
This support command programs a video BIOS into the BIOS area of an
SSD. A new video BIOS is required for a different flat panel display.
Syntax
PGMVIDEO VIDEOBIOS.DAT SSDn [/P] [/C]
Parameters
n VIDEOBIOS.DAT is the filename of the new video BIOS. For a
complete listing, see the VGA 65550 utility disk.
n SSDn is the SSD which programs the video BIOS into SSD0 or
SSD1. The BIOS is then selected by adjusting the BIOSDEV
jumper, W2[5-6].
n /P reprograms the current video BIOS. Normally, PGMVIDEO by
itself can not reprogram the current video BIOS.
n /C reprograms the video BIOS if the checksum of the video BIOS is
not correct. /C is usually a failure condition for a video BIOS when
the system will not use the new video BIOS. By default, the video
BIOS to be programmed must initially pass the checksum test.
B-11
Software utilities
PC-500 user’s manual
Example 1
To program the S64P80.DAT video BIOS (which operates the Sharp
64P80 flat panel and CRT in simultaneous display mode) into SSD1
whether or not the current video BIOS is in SSD1, enter the following
command:
PGMVIDEO S64P80.DAT SSD1 /P
Remarks
The video BIOS is typically 40K and resides in the C0000-C7FFF and
C8000-CBFFF areas. To use the new video BIOS, set the BIOSDEV
jumper, W2[5-6], to the programmed SSD. Also, enable the video BIOS
areas, C0000-C7FFF and C8000-CBFFF. To enable the video BIOS
areas, change the jumpers on W2[1-2] and W4[1-2] or change the ROM
enable options in SETUP. Change the ROM enable options and jumpers W2[1-2] and W4[1-2] accordingly to accommodate your current ROM
enable and jumper states. For complete instructions on enabling and
disabling the video BIOS, see the Console devices chapter.
If the video BIOS is programmed and no display results occur, then
adjust W2[1-2] and W4[7-9] by trying four options: on, on; on, off;
off, on; or off, off (refer to Table 7-4). Also, confirm that the VGA disable
jumper, W4[5-6] is installed. If the display still does not work, then
check the cabling and/or the video BIOS, programmed for your flat
panel. To restore the CRT/VGA display, reprogram the default video
BIOS by using the serial console to access the PC-500.
When the SCSI.DAT BIOS is combined with the video BIOS, then both
BIOSs can be programmed at once. For more information on combining
these two BIOSs, refer to the README.DOC on the SCSI utility disk.

For more information on supported video BIOS files, see the VGA 65550
utility disk and its README.TXT file. See the SETUP programs and
the Console devices chapters for more information on enabling/disabling
the video BIOS.
≡ PHDISK.EXE
Purpose
This support command creates a Save to Disk partition on an IDE hard
drive.
B-12
PC-500 user’s manual
Software utilities
Syntax
PHDISK
Remarks
This program modifies the partition table on an IDE hard drive so that
a “save to disk” can be performed. The size of the partition includes
system information such as interrupt controllers, floppy disk controller,
etc. It also includes video RAM and system DRAM contents. Since the
DRAM contents are included, the size of system DRAM (at the time
PHDISK is executed) is used in calculating the size of the partition. A
4 MB DRAM system requires more than 6 MB of partition space. Once
created, it cannot be enlarged without destroying other partitions.
WARNING!
If a partition already exists on the hard drive, this program
will destroy it! Execute PHDISK first, then install other
partitions using FDISK or other OS partitioning programs.
To use the save to disk feature, the PMISETUP SAVE-TO-DISK option
must be set to Y. The IDE drive must also be the first drive, therefore
the SETSSD /after option should be used. The save to disk feature
works with true IDE drives only.
See the FDISK command in your DOS manual for more information
about partitions.
See the SETUP programs chapter for information on PMISETUP. See
the CPU power management chapter for more information on save to
disk.

≡ REMDISK.EXE
Purpose
This support command allows access to a disk drive on a remote system
via a serial cable and standard PC style (8250 UART) serial port.
Syntax
REMDISK [/U] [/?] [/Bnnnn] [+] [/COMn]
Parameters
n /U tells REMDISK to unload itself from memory, thereby disabling
the new drive letter and freeing the memory occupied by REMDISK.
The option can only be used when REMDISK is installed from the
DOS command line. A Remote Disk installed via CONFIG.SYS
cannot be unloaded.
n /? displays a short help screen for the REMDISK program. No other
arguments are to be included on the command line when the /? is
used.
n /Bnnnn selects the baud rate for transmission. Available baud rates
are 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115k.
The default baud rate is 115k.
n + is an optional argument which specifies packet style transmission.
This is recommended for any baud rates over 19200. The default for
this option is to include the + for packet transmission.
n COMn is an optional argument which selects the communication
port. Available ports are 1 and 2. COM1 is the default port.
Note
To use the Remote Disk, both the REMDISK and the REMSERV programs must be running on their respective systems. Both programs
must use the same baud rate and packet or non-packet style transmission. It does not matter which program is installed first.
Remarks
In a Remote Disk setup, one system, the one that will share its drives, is
termed the Server. The other system, the one that will access and use
the remote drives, is called the Client. The serial ports on both systems
must be connected via a null modem cable. A cabling diagram for a
standard cable is shown below.

Run REMDISK.EXE on the Client system. This program creates a new
drive letter for the Client. REMDISK will use the next available system
drive letter. For example, if the last assigned drive was D:, REMDISK
will create a drive E:. This drive acts in all ways just like any other
drive, except for the fact that it requires the serial port to do its job.
REMDISK.EXE can be installed using a DEVICE= command in
CONFIG.SYS or from the DOS prompt.
Example 1
To install the REMDISK program from CONFIG.SYS at 19200, on
COM1, using packet style transmission, enter the following in
CONFIG.SYS and then reboot the system (remember to include the full
path to find REMDISK.EXE if not located in the root directory):
DEVICE=REMDISK.EXE /B19200 +
Example 2
To display a help screen for REMDISK, enter the following at the DOS
prompt:
REMDISK /?
Example 3
To install REMDISK from the DOS prompt or from a batch file (like
AUTOEXEC.BAT) at 9600 baud, without packet style transmission, on
COM2, enter the following;
REMDISK /B9600 /COM2
Example 4

n + is an optional argument which specifies packet style transmission.
This is recommended for any baud rates over 19200. The default for
this option is to include the + for packet transmission.
n COMn is an optional argument which selects the communication
port. Available ports are 1 and 2. COM1 is the default port.
n /S instructs REMSERV to run silently, that is without any screen
output.
n /? is an unlisted option which is used to print a short help screen for
the REMSERV program. If the /? is used, the drive letter argument
is omitted, for example:
REMSERV /?
Example 1
To select drive B: as the available Server drive at 115K baud, packet
style transmission, using COM1, you would enter the following:
REMSERV B:
Example 2
To set drive C: as the Server disk at 9600 baud, without packet style
transmission, on COM2, you would enter the following:
REMSERV C: /B9600 /COM2
Note
The Server program can be terminated at any time by pressing the

Parameters
n SSDn specifies one SSD.
n SSDm specifies two SSDs.
n /before is an optional parameter that indicates the SSDs are to be
allocated before any hard drives. The first SSD specified will be the
boot device.
n /after is an optional parameter that indicates the SSDs are to be
allocated after any hard drives. The hard drive will be the boot
device. This is the default.
B-20
PC-500 user’s manual
Software utilities
n /NoSSD is an optional parameter that specifies that no SSDs are to
be allocated.
n /? displays a short help screen for the SETSSD program. No other
arguments are to be included on the command line when the /? is
used.
n /D is an optional parameter that specifies SETSSD to use its defaults.
n /QNX+ enables the QNX drive option.
n /QNX- disables the QNX drive option (default).
n /SSD0BIOS+ reserves the BIOS area of SSD0 (default).
n /SSD0BIOS- does not reserve the BIOS area of SSD0.
Example 1
Enter the following command to enable the QNX drive compatible mode:
SETSSD SSD1 SSD0 /QNX+
Once the mode is set, the drive is no longer readable by Phoenix
PICOFA as a DOS drive. The system can boot from the QNX drive in
SSD1, when the system is programmed with a QNX drive image.
Example 2
To enable the PICOFA compatible mode, enter the following command:
SETSSD SSD1 SSD0 /QNXIf the SSDs were programmed with a QNX drive image, use PFORMAT
to reformat the SSD.
Remarks
If the boot order in SETUP is set to “A: THEN C:,” the system tries to
boot from a floppy (if one exists) and then it tries to boot from the C:
drive. The C: drive can be either an SSD or an HDD depending upon
which switch, /before or /after, was selected. If the boot order is set to
"C: ONLY," the floppy check is not performed. You may override the
order of the SSD by removing the USESETUP jumper.
When /QNX+ is enabled and when PICO FA reports to SSD1, PICO FA
communicates “+QNX/ROM.” When /SSD0BIOS- is enabled and when
PICO FA reports to SSD0, PICO FA communicates “-FULL.” Drives
PFORMATTED with /SSD0BIOS+ are not recognized when
/SSD0BIOS- is used. Drives PFORMATTED with /SSD0BIOS- are not
recognized when /SSD0BIOS+ is used. When this option is changed, use
PFORMAT again to reformat the SSD0 drive.

following command on the PC-500:
TRANSFER D:\DEMO.EXE /R /V /B57600
Then enter the following command on the remote PC:
TRANSFER C:\DEMO\DEMO.EXE /S /V /COM2 /B57600
To receive a file named D:\MYAPP.EXE from the PC-500 and name it
C:\APPS\MYAPP2.EXE on the remote PC over a serial cable connected
to COM1 on both systems at 9600 baud, enter the following command
on the PC-500:
TRANSFER D:\MYAPP.EXE /S
Then enter the following command on the remote PC:
TRANSFER C:\APPS\MYAPP2.EXE
Remarks
The TRANSFER command communicates with other XMODEM compatible file transfer programs.
The serial port on the PC-500 requires a null modem adapter when
connected to a serial port on the remote PC. See the Serial ports chapter more information.

The maximum baud rate is dependent on the processor speeds of the
remote PC and the PC-500.
The received file size is rounded up to the nearest 128 byte boundary.

REMDISK.EXE, REMSERV.EXE
≡ VDISK.SYS
Purpose
This device driver allows the user to use memory as a disk.
Syntax
DEVICE= VDISK [size [secs [dirs]]] [/E] [/NOTIFEXT]
Parameters
n size specifies the size of the VDISK in kilo (K) bytes. The default is
64K if base memory is selected. Otherwise, if /E is entered, then the
size of the VDISK is all available extended memory (size is 64K
smaller if DOS is loaded HIGH). The memory selected will be allocated from the DOS memory pool, decreasing the amount of memory
available for programs, unless the extended memory switch is used.
n secs specifies the sector size in bytes. The default is 512 bytes per
sector. This value must be 128, 256, 512 or 1024. All other values
are not valid and the default of 512 bytes will be used.
n dirs specifies the number of root directory entries. The default is 64
directory entries. There may be any number of root directory entries
between 2 and 1024. If an odd number is given, it will be rounded
up to the nearest multiple of 16, in order to fill the entire sector.
n /E causes VDISK to use extended memory (memory above the 1 MB
boundary) instead of DOS program memory for the disk.
n /NOTIFEXT causes the virtual drive to not be installed if extended
memory exists.
Note
Interrupts are turned off during the transfer of data from extended
memory to conventional memory.
The VDISK increases the resident size of DOS.
B-26
PC-500 user’s manual
Software utilities
Remarks
VDISK allows the user to partition some of the computer's memory as a
disk. This disk is called a RAM disk or Virtual Disk. A RAM disk is
much faster than either a floppy or hard disk. The RAM drive can use
either standard DOS program memory or extended memory (above
1 MB) for the disk.
Any data on the VDISK is lost when the system power is turned off.
Example 1
DEVICE=VDISK.SYS
The above example builds a 64K RAM disk in DOS memory.
Example 2
DEVICE=C:\DOS\VDISK.SYS 220 /E
This example builds a 220K RAM disk in extended memory. The
VDISK device driver is loaded from the C: drive and the \DOS directory. VDISK assumes the default 512 byte sector size, and 64 directory
entries.
Example 3
DEVICE=VDISK.SYS 45 128 18
The above example builds a 45K RAM disk in DOS memory. There will
be 128 byte sectors and 18 root directory entries.
Example 4
DEVICE=VDISK.SYS /E
On a 2 MB system, the above example allocates a 1024K drive in extended memory (960K is allocated if DOS is loaded HIGH).

≡ Using QNX on the PC-500
To use QNX on the PC-500, follow the steps below:
1. Boot from a floppy or a hard drive that has QNX installed on your
system.
2. Program SSD1 with the QNX image. See the Programming QNX into
SSD1 section below.
3. To boot from SSD1 with QNX, execute SETSSD SSD1 /QNX+.
Programming QNX into SSD1
The PC-500 contains a reserved 192K area located in front of the SSD1
flash. The EFSYS.500 driver from Octagon reserves this space automatically. Use the sample files from Octagon’s QNX utility disk to
program QNX into SSD1.
Note
When QNX+ is in the SETSSD command line, i.e.
SETSSD SSD1 SSD0/QNX+
then the QNX drive option is enabled. Once your system is in the QNX
mode, SSD1 cannot be used as a drive from DOS. TESTRFA will not
work on SSD1.
≡ Using M-Systems DiskOnChip (DOC)
To use the M-Systems DiskOnChip (DOC) module with your PC-500,
follow these steps:
1. Run:
SETSSD SSD1 /before
2. Power off the PC-500.
3. Confirm that the BIOSDEV jumper is set to SSD1.
4. Make sure SSD0 is jumpered for flash by configuring W5[1-2, 3-4, 5-6,
9-10] W2[7-8].
5. Install the DOC module into SSD0. Make sure to orient pin 1 on the
DOC module with pin 1 on SSD0.
C-1
Third party support
PC-500 user’s manual
WARNING!
Installing the DOC module into the wrong position on SSD0
of the PC-500 board will permanently damage the DOC
module.
6. Power on the PC-500.
7. Execute:
DOCPRGO /F:OCT1202.BIN /W
Note
The DOCPRGO.EXE and the OCT1202.BIN are on the DOC utility
disk.
8. Reset your system.
9. Execute:
TFORMAT 2 /BOOTSIZE:128K
Note
To access the DOC module, execute the TFORMAT command line at the
same time you execute the operating system.
10. Reset your system.
11. Access the DOC drive as drive D:.
Note
If a hard disk is installed, change Step 9 to the following command:
TFORMAT 3 /BOOTSIZE:128K
Then access the DOC drive as drive E: (Step 10).
Booting from the DOC drive
1. Add an operating system to the DOC. For ROM DOS, use the SYS
command.
2. Execute:
SETSSD SSD1 /after
3. Reset the system.
